SPECIFICATION forming-part 0f Letters Patent NO. 678,089, dated July 9, 1901.

Application filed September 4. 1900. Serial No. 28,878. (No model.)

To @ZZ whom it may concern:

Be it known that I, FRANCIS H. YOUNG, a citizen of the United States, residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Roller-Bearings and Lubricators, of which the following is a full Vand complete specification, such as will enable those skilled in the art to which it apperf tains to make and use the same. l

This invention relates to journal-bearings for railway-cars; and the object thereof is to provide an improved bearing of this class and means for automatically oilin'g or lubricating the journals thereof; and with this and other objects Vin view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompany-V ing drawings form a part, in which the sepaf tral vertical section at right angles to the section shown in Fig. 2, takenon the line 3 3'of Fig. l; and Fig. 4, a perspective view of a bear# ing-frame which I employ, said frame being composed of separate parts, which are shown detached in this figure.

In the drawings forming part of this spec-iL.

ication I have lshown at a an ordinary journal box or casing such as is usually employed for inclosing bearings of the class specified, and this box or casing may be of'any desired construction. provided with a rear wall a2, through which the car-axle b passes, and the said axle b is provided with the usual'journal h2, the end of which is provided with a circular head b3.

Mounted in the top of the box or casing a2 is a journal-bearing frame c, in which are placed two rollersd, earch of which is provided at each end with a journal d2, and the journals d2 t in small journal-boxes d5, set into theopposite sides of the bearing-frame.

The said box creasing a isY The bearing-frame c or the side thereof adjacent to the rear wall a2 of the box or casing a is cut out segmentally, as shown at c2, to form a space in which the axle b works, and the front wall of the said bearing-frame c is similarly cut out, as shown'at c3, to form a space in which the head b3 of the journal b2 works. The rollers d are much greater in di- ;ameterthan the journal band are substantially of the same length as said journal and iit between the head b3 thereof and the annular shoulder h4 at the inner end of said journal, and the entire weight borne by the journal is placedupon the bearing-frame c, which is supported by the rollers d on said journal,

and anylateral movement of the journal or of the'rollersd is prevented by the head b3 of the journal and the annular shoulder b4 at'the inner end thereof, said parts operating l.against the opposite ends of said rollers in order to accomplish this result, as wil understood.

AMounted in thebottom of the box or casingct is a float comprising aframe e, composed` of any desired material, and in which is revolubly supported a oat-roller g, whichfis adapted to turn in its bearings 72 and said roller g may be composed of any desired ma-r terial, and, as shown in the drawings, is made hollow, and the length thereof is substantially equal to the length of the journal h2 between thehead h3 thereof and the annular shoulder h4. The float-frame e may also be made of any desired material, and in practice the bottom of the box or casing a is partially filled with oil or any suitable lubricating material, as shown at 7e in Fig. 2, and in the 0peration of the apparatus the cylindrical and revoluble flo'atroller gis always held in contact with the journal b2 and is constantly revolved thereby, and said journal is thus kept constantly lubricated, and the rollers d comingin contact with said journal are also constantly lubricated.

The bearing-frame c' is composed of two separate parts, as shown in Fig. 4, in order to facilitate the placing-of the rollersd therein for the purpose ofrenewing said rollers when necessary, and-in making said bearing-frame c I preferably divide the opposite sides thereof centrally, as shown at m, and form the separate parts so that they will overlap, as

l be readily- IOO The bearing-rollers d may be made of any1 desired diameter and are preferably made from two to three times the diameter of the journal b2, and by means of my improved construction I provide a journal bearing which is perfectly lubricated at all times, and which is also strong and durable and by means of which friction i-n operation is reduced to a minimum.

The frame c is supported or steadied by the diamond frame now in use. The box or casing a is in practice slipped on over the spindle or journal of the axle, and the frame c, with the rollers CZ mounted therein, is then placed in position on the top of the journal or spindle inside of the box or casing a, the box or casing a being open at the top and provided With castings or supports for the diamond frame referred to, and theparts are all bolted together in the usual manner.

By making the frame c of two parts I provide means whereby repairs may be made to the journals of a car or the bearings thereof Without taking the car to the general shops.

of the road, it being understood that new bearing-rollers may be put in this frame c Wherever and Whenever necessary, whereas if the frames were made integrally it Would be impossible to make repairs without taking the car to the shop. It will also be apparent that by making the bearing-rollers in the frame c of greater diameter than the journal the oil or other lubricant, the float, consisting of the frame and roller mounted therein, serving for this purpose.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- The combination with an axle having a journal provided with a circular head at its outer end, and an annular shoulder at its inner end, of a box or casing through the rear wall of which the journal passes, a floating frame mounted in the lower portion of the box and a cylinder carried by said iioating frame and adapted to revolve in contact with said journal, and which is of the same length, and a bearing-frame mounted in the top of the box or casing and provided with two rollers of greater diameter than the journal and of the same length, the construction and arrangement being such that the said rollers operate between the head of said journal and the annular shoulder at the inner end thereof and t between the same, substantially as shown and described'.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing Witnesses, this 31st day of August, 1900.

FRANCIS I-I. YOUNG.
